Alison Cut Back ValveThis valve is the converter flow valve. This valve controls fluid to the converter clutch and cuts back pressure from 250 psi ( or so ) to 145 psi when the converter clutch applies. This valve will bring that pressure to a more acceptable 170 190 psi, and much more depending on application. This valve is very important in high horsepower applications to hold the most extreme conditions. 01 07 Duramax, include a note with year of your truck at checkout.
